This book provides a standardized set of protocols for measuring soil properties, to facilitatte corss-site synthesis and evaluation of ecosystem processess. The book should be of interest to a rather broad range of ecologists, agronomists, and soil scientists. It is the second volume in the Long-term Ecological Research Network series.

The semiarid shortgrass steppe is the warmest, driest, and lowest in primary production of grasslands in central North America. This book is an enormously rich source of data and insight into the structure and function of semiarid grassland.

This volume will lay out the best methods for measuring net primary productivity (NPP) in ecological research. Primary productivity is the rate at which energy is stored in the organic matter of plants per unit area of the earth's surface. NPP is the beginning point of the carbon cycle, so our ability to accurately measure NPP is important. The book includes chapters for each of the critical biome types to offer special techniques that work best in each biome. For example, there are chapters that discuss grassland ecosystems, urban ecosystems, marine pelagic ecosystems, forest ecosystems, and salt marsh ecosystems, among others. All 26 LTER sites will be expected to collect and report data using these methods, but ecologists more generally should also find these methods useful and authoritative. Currently no standard methods or standards exist. Measuring NPP is fundamental to many ecosystem studies at thousands of sites, and having identified standards and methods would be extremely useful for comparing measurements among sites and for compiling a broad scale understanding of the environmental, biological, andnutrition controls on NPP. This book would resemble the Standard Soil Measurement volume in the LTER series in that it reaches well beyond any single LTER site to apply to any ecosystem. It should be rather more widely used than the soil measurements volume, in that measuring productivity is so fundamentalto any ecological analyses as well as agronomy, forestry, fisheries, limnology and oceanography.

This book explains how to foresee and manage ecosystem changes in the Luquillo Mountains in Puerto Rico, by looking at underlying causes and effects. The lessons from the abiotic and biotic environments, populations, and ecosystems in this region apply to analogous forest biomes in Central and South America, as well as around the world.

Presents the work that has been done and the understanding and database that have been developed by work on climate change done at the Long-Term Ecological Research (LTER) sites. This book pulls together information from all 20 research sites.

This work aims to provide a complete overview of an alpine ecosystem, based on the long-term research conducted at Niwot Ridge, Colorado, USA. The alpine ecosystem features conditions near the limits of biological existence, and is a useful laboratory for asking more general ecological questions.

This book is the first in a series of planned synthesis volumes from sites funded by the National Science Foundation's Long-term Ecological Research Program. This volume focuses on over 15 years of research at the Konza Prairie in NE Kansas and provides a unique perspective on the structural and functional ecology of a grassland ecosystem that once covered most of central North America.

The latest volume in the Long-Term Ecological Research series, presenting two decades of research on the sustainability of temperate, row-crop ecosystems in the Midwestern United States.

For several years in the USA, scientists, university faculty, agriculturalists, natural resource managers, and the public have collaborated on research to understand ecological principles and their application to land management in the Chihuahuan Desert of New Mexico. This book is a synthesis of what has been learned from these collaborations.

Presents 20 years of work at the North Temperate Lakes Long-Term Research Site. This site-synthesis volume provides the information base for the ecology of temperate lakes, and a general assessment of the role of lakes within their landscapes. It is of interest to American limonologists and general ecologists.

The first volume in the "Long Term Ecological Research Network" series, this book summarizes the state of knowledge about biodiversity in drylands, and seeks to identify questions and strategies for future research and to lay out guidelines for management of biodiversity in desert and semi desert regions.

The latest volume in the LTER series, this book presents the results and finding of the Long-Term Ecological Research site in the Alaskan Arctic, discussing Arctic ecology from a variety of perspectives and disciplines.

The Coastal Everglades presents a broad overview and synthesis of research on the coastal Everglades, a region that includes Everglades National Park, adjacent managed wetlands, and agricultural and urbanizing communities. Contributors for this volume are all collaborators on the Florida Coastal Everglades Long-Term Ecological Research Program (FCE LTER). The FCE LTER began in 2000 with a focus on understanding key ecosystem processes in the coastalEverglades, while also developing a platform for and linkages to related work conducted by an active and diverse Everglades research community. The program is based at Florida International University in Miami, but includes scientists and students from numerous other universities as well as staff scientists at keyresource management agencies, including Everglades National Park and the South Florida Water Management District.Though the Everglades landscape spans nearly a third of the State of Florida, the focus on the coastal Everglades has allowed the contributors to examine key questions in social-ecological science in the context of ongoing restoration initiatives. As this book demonstrates, the long-term research of the FCE LTER has facilitated a better understanding of the roles of sea level rise, water management practices, urban and agricultural development, and other disturbances, such as fires and storms,on the past and future dynamics of this unique coastal environment. By comparing properties of the Everglades with other subtropical and tropical wetlands, the book challenges ideas of novelty while revealing properties of ecosystems at the ends of gradients that are often ignored. It also providesinsights from, and encouragement for, long-term collaborative studies that inform resource management in similarly threatened coastal wetland landscapes.

A long-term study of the effects of clearcutting on forest and stream ecosystems.
